Abstract :
We demonstrate wavelength-shift-free multichannel width-tunable NRZ-to-RZ modulation format conversion using single SOA-based Sagnac interferometer. Optimization of the control clock power results in the considerable improvement of receiver sensitivity and input-power dynamic range to over 20 dB.
